摘　　要：在基本随机变量的概率特性已知的情况下,采用最大可能点摄动分析法和灵敏度分析方法,通过计算机程序可以直接实现螺旋管簧的可靠性参数灵敏度分析,迅速准确地得到螺旋管簧的可靠性参数灵敏度信息,研究了设计参数的改变对螺旋管簧可靠性的影响,为螺旋管簧的可靠性设计提供了理论依据。On the condition of known probabiliatic characteristics of basic random variables, based on the theory of the most probable point perturbation method for reliability design with normal distribution parameters and the theory of sensitivity analysis, reliability sensitiyit analysis for coil tube-springs was studied and its numerical method was presented. The respective program can be used to obtain the information of reliability sensitivity analysis, and the effects of design parameters on the reliability of coil tube-springs were studied. The method presented in this paper provides theoretical basis for the reliability design of coil tube-springs.
